DA Fee Abstraction

Sunrise introduces "DA Fee Abstraction," a mechanism that allows developers to access blob spaces on Sunrise without paying direct fees. Instead, developers can provide liquidity to Sunrise liquidity pools to gain access to data availability services. This innovative approach reduces entry barriers for developers while maintaining the economic sustainability of the network.

Key Features

1. Liquidity-Based Access:

   • Developers provide liquidity to pools in the x/liquiditypool module.

   • This contribution supports the network's overall liquidity and stability.

2. Reward Mechanism ($vRISE):

   • Liquidity providers receive $vRISE tokens as rewards.

   • These tokens can be used to pay for data availability transactions.

3. Fee Segregation:

   • Data availability transactions can use $vRISE tokens.

   • Other transaction types still require $RISE tokens for fees.

4. Economic Sustainability:

   • Ensures Sunrise can provide data availability services without direct fee revenue.

   • Creates an alternative economic model that benefits both the network and developers.

Core Functionality

Liquidity Provision and DA Access

When developers want to access data availability services:

• They provide liquidity to selected pools in the x/liquiditypool module.

• They receive LP tokens representing their share of the pool.

• They earn $vRISE tokens through liquidity mining.

• These $vRISE tokens can be used to pay for data availability transactions.

Workflow: DA Fee Abstraction Process

Below is a sequence diagram illustrating how the DA Fee Abstraction works:

Benefits

1. Lower Entry Barriers:

   • Developers can access data availability services without upfront token costs.

   • Promotes greater adoption of Sunrise's data availability layer.

2. Liquidity Enhancement:

   • Encourages developers to provide liquidity to the network.

   • Improves overall market depth and reduces slippage.

3. Sustainable Economics:

   • Creates a virtuous cycle where DA usage drives liquidity.

   • Liquidity providers are incentivized through $vRISE rewards.

Example Usage

Providing Liquidity and Using DA

import { SunriseClient } from "@sunriselayer/client";
import { MsgCreatePosition } from "@sunriselayer/client/types";

async function provideLiquidityAndUseDA() {
    // Connect to Sunrise
    const client = await SunriseClient.connect("https://sunrise-rpc.example.com");
    
    // Step 1: Provide liquidity to a pool
    const msgCreatePosition = {
        sender: "sunrise1...",
        poolId: 1,
        tokenBase: { denom: "urise", amount: "1000000" },
        tokenQuote: { denom: "uusdc", amount: "1000000" },
        lowerTick: "-10000",
        upperTick: "10000"
    };
    
    // Step 2: Submit DA data using vRISE for fees
    const msgPublishData = {
        sender: "sunrise1...",
        data: "0x...", // Your data to publish
        fee: { denom: "uvRISE", amount: "100000" }
    };
    
    // Execute transactions
    const result = await client.executeTransactions([msgCreatePosition, msgPublishData]);
    console.log("Liquidity provided and DA accessed:", result);
}
